elasticsearch can't get data from mongodb

[hordemark]

I had install mongodb river and head plugin in the docker.
When i execute the following code, it can't synchronize data from mongodb.
But it can work well not use docker.
Anybody get trouble ?

curl -XPUT 'http://127.0.0.1:9200/_river/mongodb_source/_meta' -d '{ "type": "mongodb", "mongodb": { "db": "andes", "collection": "source", "host": "192.168.90.46", "port": "27017" }, "index": { "name": "mongoindex_source", "type": "source" } }'
